FUV Group is a technical and innovation-driven company founded in 2005 by architect and field researcher Theodoros Sotirios Tountas. It focuses on bridging scientific knowledge with applied construction practices. Through its subsidiaries and international partnerships, it delivers high-performance materials, airtightness solutions, and sustainable building technologies for both residential and industrial applications.

Its dedicated subsidiary FUV Products (www.fuvproducts.gr) introduced to the Greek market Supafil cavity wall insulation by Knauf Insulation, natural building materials by Naturalia-Bau, and airtightness systems by PosaClima, specializing in existing building renovation and passive construction components.

FUV Group has conducted the largest recorded number of airtightness tests in Greece, covering both energy efficiency and fire protection compliance (including EN 9972 and EN 15004 standards), promoted via www.aerosteganotita.gr. It is actively involved in Blower Door field testing, technical training, and on-site verifications, offering services for Passive House, LEED, and advanced hospital and datacenter infrastructure.

Through www.masstimbergreece.gr, FUV also promotes mass timber (CLT) construction, contributing to the transition toward carbon-neutral buildings.

Beyond product implementation, FUV Group supports and funds applied field research, presenting findings at international conferences and driving professional awareness in the fields of airtightness, sustainable renovation, and performance verification.

We work where innovation meets research — and where construction meets measurable quality, safety, and sustainability.
